A strike planned by London Underground track patrol workers has been suspended after progress in talks.

Members of the Rail, Maritime and Transport (RMT) union were due to walk out for 24 hours at 6.30am on Friday in a row over the use of private contractors to "casualise" jobs.

The dispute flared over the use of agency workers to check for any track defects.

The RMT said London Underground will suspend the training and assessment of non-permanent employees for track patrolling purposes for two weeks and the union will suspend its planned industrial action for the same period.
